Cellular technologies have advanced enormously; one of the main developments is the emergence of 4G technology. It’s a term that you’ve surely encountered in your daily life, but what is 4G? And is LG K40S 4G capable? We will answer these and other questions related to LG K40S 4G technology in the following article.
is the LG K40S4G-compatible phone?
Yes. LG K40S is 4G capable
How to check the existence of 4G on LG K40S
Nowadays, it is inevitable to purchase a 4G-capable phone, because most internet users require a good internet connection. To know whether the phone is 4G-capableor not, you can use multiple means.
An easy way when you pick the phone in your palm is just turning on the cellular data, if the LG K40S 4G data is on, then you will see an icon at the top of the screen, in the status bar. It might be 4G, 4G+, LTE, or LTE+ according to your carrier.
The absence of that symbol means that you are not using 4G at that specific moment, and it doesn’t always mean that your phone doesn’t support 4G. And that takes us to the second way.
Check your phone specifications on the manual, or in the phone box. If you lose both of them, you can still check that on the official website (or any other reliable website) using the device name or model number.
Another way is to check the settings: Go to your settings and fetch network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone has 4G you will find a 4G or an LTE option. If you don’t see either of them, then your smartphone isn’t 4G-enabled.
How to switch to 4G on LG K40S?
If you would like to activate your LG K40S 4G network, then follow the instructions (it might vary slightly from the settings on your own device):
1- From Home screen, choose Apps.
2- From the Apps tab, select Settings.
3- Select Network.
4- Make sure to turn on the Mobile data.
5- Tap Mobile networks.
6- Select the SIM card you want to set.
7- Choose Network mode.
8- Choose 4G or LTE option.
Note: If you would like to turn off 4G then choose a lower network type (such as 3G).
What 4G is on LG K40S?
4G is the fourth generation of cellular communication technologies, it comes just after 3G and before 5G. Although 5G is the strongest technology available in the world, 4G is still the fastest most spread technology.
4G comes with fast uploading and downloading speeds, exceeding the previous 3G technology, and it also has lower latency, allowing users to try much more things using their phones, things such as live conferencing.
To be more specific, 4G is a term assigned by the International Telecommunication Union (ITU), and it is also a commercial expression used by wireless carriers to express a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for LG K40S 4G to be useful, it should be suitable with the protocols used by local wireless carriers.
Feature of 4G technology on LG K40S
4G was developed to provide a more reliable internet connection on mobiles, and that’s truly what it did. 4G technology allows much enhanced downloading and uploading speeds than 3G.
The average 3G speed is around 1.5 to 9 Mbit/s, while the average 4G internet speed is between 15 to 90 Mbit/s, it can achieve as high as 900 Mbit/s.
Another prominent criterion of 4G, is its low latency. We can simplify latency and say it’s the time needed to transmit data or the delay between the action and the actual response. Lower latency means a better user experience. 4G Latency is better than 3G by double. The average 4G latency is 50 ms.
With the aid of the VoLTE standard, 4G now offers better voice quality in phone calls and gives users the ability to browse the internet while making calls.
All of these advantages combined with the low cost of 4G increased the use of LG K40S 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
What are 4G bands? And which bands are available in the LG K40S?
4G and other cellular networks use radio waves to communicate data. These waves have different lengths and frequencies. To prevent interference between signals, governments and the ITU decided which regions use which frequencies for 4G.
Each region has been allocated certain frequency intervals called bands. Band number 7 and band number 28 (for example) are used at the world level.
What you should know as a consumer is that each cellular operator provides certain bands according to the area, and different phones enable different bands. So you should make sure that your LG K40S supports the bands offered by your local cellular provider.
Here are the LG K40S4G-enabled bands:
1, 3, 7, 8, 20;.
